BACKGROUND

1. Field of the Invention

The present invention generally relates to accessing communication networks. More particularly, the invention relates to the automatic access of wireless communication networks.

2. Description of Related Art

The increasing use of the networks to access information has resulted in a greater dependence on network communication for a variety of activities. With this dependence comes the growing expectation that network access will be ubiquitous. Network access for mobile users has been particularly enhanced by improvements in wireless technology. Various cellular (e.g. GSM, CDMA and the like), Wi-Fi (i.e. IEEE 802.11), WiMAX (i.e. IEEE 802.16), and other technologies have enabled a wide range of access options for a potential network user. Many wireless access points or “hotspots” are accessible only with local geographic regions—in some cases as small as a specific business or other address. In addition, strategically placed hotspots may provide public or private network access for a diverse group of people.

The owners or managers of hotspots often require password and the like to enable user access. As a result, a user of multiple hotpots may have to store, remember, or otherwise manage a large number of passwords. Many users may store their passwords on a laptop computer they use to access the hotspot. However, not all devices capable of accessing hotspots are laptop computers; cellular phones, personal digital assistants (PDAs), and many other devices are now capable of wireless access. Unfortunately, users often cannot easily enter the password on the device or store the password within the device. For example, some devices capable of wireless access may not have a keyboard. Even when a device includes a keyboard, the keyboard is often small and may be of limited functionality, especially for users with limited finger dexterity.

When users store passwords on a laptop computer, the user must first access the laptop computer and store the correct password within the computer. When a password changes, the user is required to update the password within the computer. Additionally, having the username and password stored in the device presents a security problem should the device be lost or stolen.

Further, users are typically required to enter a password, username, and navigate a website to obtain network access. This process is time consuming and the user may enter the wrong information and be forced to re-enter data.

When users enter a password manually, they are less apt to remember difficult passwords. As a result, simple password access is susceptible to hacking and may compromise the user's network access, the hotspot, and/or the user's personal information. Moreover, the user's network access may be stolen if the user's simple password is hacked or simply guessed.

Connecting to wireless networks has traditionally been a complex process for users of wireless devices for other reasons. Typically, the user enters an area where two or more Wi-Fi networks are present, selects the Wi-Fi function on their laptop, and views a series of ‘scan results’ listing the available Wi-Fi networks. In one example, the listing of available Wi-Fi networks comprises a list of Wi-Fi network SSID identifiers. Users must often identify which Wi-Fi networks do not have encryption or other security mechanisms (e.g., a login page). To add to user frustration, some of the wireless networks may be functional while others may be misconfigured in such a way that renders the network unuseable.

The user typically makes an arbitrary decision which Wi-Fi network to connect to based on the listing. In making a decision of which Wi-Fi network to connect, the user typically does not know whether the selected Wi-Fi network will provide adequate quality of service or even if the network will be able to provide an IP address via Dynamic Host Configuration Protocol (DHCP).

Wi-Fi networks, in homes, business and Hotspots can be identified by a human readable name (e.g., the SSID identifier). An example of an SSID identifier might be “My Home Network,” or “tmobile.” In addition to the SSID identifier, when a secure Wi-Fi network is first connected, various security parameters may need to be entered to configure either the WEP (Wired Equivalency Privacy), WPA (Wi-Fi Protected Access), or other security schemes.

Many Wi-Fi networks are left “open” with no encryption mechanism. Often this is intentionally done by the owner of the Wi-Fi network to enable easy access without the need for a WEP or WPA network key. However, Wi-Fi networks are also left “open” with no encryption mechanism because the owner is either unaware that the network is open or does not know how to secure the network. As a result, although the Wi-Fi network is “open,” the network is not being intentionally shared. Such networks are very convenient for a user of a Wi-Fi enabled device, however, the user may not know that they do not have permission to use an otherwise open network.

Unfortunately, some countries have instituted laws which make it illegal to access a wireless network that is not purposefully shared. As a result, users may be unaware that an “open” network is not shared and, as a result, unintentionally commit a criminal act by accessing the network.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention provide systems and methods for providing network credentials. In exemplary embodiments, a credential server receives a request for network credentials from a digital device at a hotspot. The request may be formatted as a standard protocol which is relayed from the hotspot to the credential server. The credential server may identify a network record based on at least some information contained within the request and transmit network credentials associated with the network record to the digital device. The digital device may receive the network credentials and provide them to network device in order to obtain network access.

In various embodiments, a rules server may identify a preferred network from a plurality of available networks that the digital device may connect based on a variety of network attributes. In one example, a digital device may scan a physical region for available networks and generate a list of available wireless networks. The list may be provided to a rules server which identifies and retrieves a network profile for each wireless network on the list. The rules server may then compare each network profile (e.g., via attributes contained within each profile) to select a preferred network from the list. The rules server may then transmit the wireless network selection to the digital device which may then access the network.

In some embodiments, the digital device accesses the selected wireless network using credentials provided by the credential server. In one example, when the rules server selects the preferred wireless network, the rules server (or another server in communication with the rules server) may simultaneously (or nearly simultaneously) provide a credential request response including network credentials associated with the selected wireless network.

FIG. 1 illustrates a diagram of an environment 100 in which embodiments of the present invention may be practiced. In exemplary embodiments, a user with a digital device 102 enters a hotspot. The digital device 102 may automatically transmit a credential request as a standard protocol over a network device 104. The credential request may be forwarded to a credential server 116 which, based on the information contained within the credential request, transmits a credential request response back to the digital device 102. The credential request response contains network credentials which the digital device 102 may provide to the network device 104, the authentication server 108, or the access controller 112 to obtain access to the communication network 114.

In various embodiments, a hotspot comprises the network device 104, the authentication server 108, the DNS server 110, and the access controller 112 which are coupled to the local area network 106 (e.g., a “walled garden”). The network device 104 may comprise an access point which allows the digital device 102 to communicate with the authentication server 108, the DNS server 110, and the access controller 112 over the local area network 106. The digital device 102 may comprise a laptop, mobile phone, camera, personal digital assistant, or any other computing device. The authentication server 108 is a server that requires network credentials from the digital device 102 before allowing the digital device 102 access the communication network 114. The DNS server 110 provides DNS services over the local area network 106 and may relay requests to other DNS servers (not shown) across the communication network 114. The access controller 112 is an access device such as a router or bridge that can allow communication between devices operationally coupled to the network device 104 with devices coupled to the communication network 114.

Although the hotspot in FIG. 1 depicts separate servers coupled to the local area network 106, those skilled in the art will appreciate that there may be any number of devices (e.g., servers, digital devices, access controllers, and network devices) coupled to the local area network 106. In some embodiments, the local area network 106 is optional. In one example, the authentication server 108, the DNS server 110, and the access controller 112 are coupled directly to the network device 104. In various embodiments, the authentication server 108, the DNS server 110, and the access controller 112 may be combined within one or more servers or one or more digital devices. Further, although FIG. 1 depicts wireless access, the digital device 102 may be coupled to the network device 104 wirelessly or over wires (e.g., such as 10 baseT).

In order to access the communication network 114, the authentication server 108 may require the digital device 102 to provide one or more network credentials for access to the hotspot. The network credential may comprise, for example, a username and password for an account associated with the hotspot. In alternative embodiments, network credentials other than a user name and password may be utilized.

According to exemplary embodiments, the digital device 102 may dynamically acquire the network credentials from the credential server 116. The digital device 102 may send a credential request comprising an identity of the digital device 102 (or the user of the digital device 102) and details about the network device 104 (e.g., name of the network device 104 or Wi-Fi service provider) to the credential server 116.

In one example, when the digital device 102 enters the hotspot, the network device 104 may provide an IP address to which DNS queries may be submitted, for example, via DHCP (Dynamic Host Configuration Protocol). The credential request may be formatted as a standard protocol. In an example, the credential request may be formatted as a DNS request. The credential request may be a text record request (e.g., TXT), which comprises a standard record type such that the network infrastructure (e.g., the access controller 112) will not block the request. More details regarding the process for acquiring network credentials are provided in co-pending U.S. patent application Ser. No. 11/899,697, entitled “System and Method for Acquiring Network Credentials,” filed Sep. 6, 2007, and incorporated by reference herein.

In some embodiments, the credential request is received by the DNS server 110 which may forward the credential request to the credential server 116 for the network credential. In exemplary embodiments, the credential server 116 may perform a lookup to determine the proper network credential(s) to send back to the DNS server 110 which forwards the network credential back to the requesting digital device 102. In various embodiments, the proper network credential(s) are sent from the credential server 116 to the digital device 102 over the same path as the transmission of the credential request.

Although only one DNS server 110 is depicted within FIG. 1, the credential request may be forwarded through any number of servers, including but not limited to DNS servers, prior to being received by the credential server 116. In other embodiments, the credential request is forwarded directly from the network device 104 to the credential server 116.

In some embodiments, a credential request response from the credential server 116 may comprise the username, password, and/or login procedure information. The login procedural information may comprise, for example, HTML form element names, a submission URL, or a submission protocol. In some embodiments, the network credential response may be encrypted by the credential server 116 using an encryption key associated with the digital device 102 prior to transmission back to the digital device 102.

Once the digital device 102 receives the network credential response, the digital device 102 may submit the network credential (retrieved from the network credential response) to the network device 104 in an authentication response. In exemplary embodiments, the authentication response may be forwarded to an authentication server 108 for verification. In some embodiments, the authentication server 108 may comprise an AAA server or RADIUS server. More details regarding the process for obtaining network access are provided in co-pending U.S. patent application Ser. No. 11/899,638, entitled “System and Method for Obtaining Network Access,” filed Sep. 6, 2007, and incorporated by reference herein.

It should be noted that FIG. 1 is exemplary. Alternative embodiments may comprise more, less, or functionally equivalent components and still be within the scope of present embodiments. For example, as previously discussed, the functions of the various servers (e.g., DNS server 110, credential server 116, and authentication server 108) may be combined into one or two servers. That if, for example, the authentication server 108 and the DNS server 110 may comprise the same server, or the functionality of the authentication server 108, the DNS server 110, and the access controller 112 may be combined into a single device.

FIG. 2 is a block diagram of an exemplary credential server 116. The credential server 116 comprises an authentication module 200, a network module 202, a credential request module 204, a credential request response module 206, an encryption/decryption module 208, a network record storage 210, and an encryption key storage 212. A module may comprise, individually or in combination, software, hardware, firmware, or circuitry.

The authentication module 200 may be configured to authenticate the credential request and provide security to the credential request response. In various embodiments, the digital device 102 may encrypt or digitally sign the credential request using an encryption key (e.g., a shared encryption key or an encryption key that is a part of a key pair). The authentication module 200 may authenticate the credential request by decrypting the credential request with the proper encryption key retrieved from the encryption key storage 212. In one example, the digital device 102 generates a hash of the credential request and stores the hash within an encrypted portion of the credential request. The authentication module 200 may decrypt the credential request, generate hash of the credential request response, and compare the generated hash to the hash contained within the credential request for authentication.

In other embodiments, the digital device 102 may generate a nonce (i.e., a random value) and store the nonce within a portion of the credential request that is digitally signed. The authentication module 200 may decrypt the digital signature to authenticate the credential request and retrieve the nonce. In various embodiments, when the credential request response module 206 generates the credential request response (described hereafter), the authentication module 200 may include the nonce within the credential request response. The authentication module 200 or the encryption/decryption module 208 may then encrypt the credential request response. When the digital device 102 decrypts the credential request response, the digital device 102 may retrieve the nonce from the credential request response and compare the nonce to the nonce that was transmitted within the credential request for further authentication.

The network module 202 may be configured to receive the credential request and transmit the credential request response over the communication network 114.

The credential request module 204 may receive the credential request from the network module 202. The credential request may be a standard protocol. In one example, the credential request is a UDP protocol (e.g., DNS).

In exemplary embodiments, the credential request module 204 may retrieve the DDID and the SSID from the credential request. The DDID may identify the digital device 102, the user of the digital device 102, and/or the user associated with a network record. The SSID may identify the hotspot or the service provider (i.e., operator) of the hotspot.

The credential request module 204 or the credential request response module 206 may identify a network record based on the DDID and the SSID. A network record is a record associated (either directly or indirectly (e.g., a relational database)) with the DDID and the SSID. In one example, a network record contains network credentials necessary to provide network access to a digital device 102 associated with the DDID at the hotspot associated with the SSID. Network records may be stored within the network record storage 210.

The credential request response module 206 may generate the credential request response. In various embodiments, the credential request response module 206 receives the network credential associated with the DDID and SSID from the network record. In some embodiments, the network credential may comprise a credit card number. In one example, the digital device 102 receives the network credential, retrieves the credit card number, and provides the credit card number to the authentication server 108. In some examples, the authentication server 108 may then charge a fee to a credit card associated with the credit card number or use the information to confirm the identity of the user prior to granting network access.

Further, in various embodiments, the network credentials may comprise login procedural information. In one example, the credentials include a username and password which are to be provided within a form (e.g., an authentication form) retrieved from the authentication server 108 by the digital device 102. In some embodiments, the login procedural information may instruct the digital device 102 to populate specific fields within the form with the network credentials before submitting the completed form to the authentication server 108. Those skilled in the art will appreciate that there are many ways to provide credentials to the authentication server 108. The process of providing the credentials to the authentication server is further discussed in co-pending U.S. patent application Ser. No. 11/899,638, entitled “System and Method for Obtaining Network Credentials,” filed Sep. 6, 2007.

The credential request response module 206 or the encryption/decryption module 208 may encrypt the credential request response with an encryption key associated with the DDID or the credential request. In one example, the credential server 116 stores one or more shared encryption keys. Each shared encryption key may be shared by at least one digital device 102. The credential request response module 206 may encrypt the credential request response with the shared encryption key associated with the digital device 102 (e.g., the shared encryption key may be associated with the DDID). The credential request response module 206 or the encryption/decryption module 208 may also encrypt the credential request with an encryption key that is part of a key pair. There may be many ways in which the encryption/decryption module 208 encrypts the credential request.

The encryption/decryption module 208 may decrypt the credential request and encrypt the credential request response. As previously discussed, the encryption/decryption module 208 may decrypt the digital signature of the credential request. In one example, the encryption/decryption module 208 decrypts the digital signature based on an encryption key that is associated with the DDID contained within the credential request. The encryption/decryption module 208 may also encrypt the credential request response. In one example, the encryption/decryption module 208 encrypts the credential request response based on an encryption key associated with the DDID (e.g., a shared encryption key or an encryption key that is part of a key pair).

In various embodiments, the encryption/decryption module 208 may encrypt the network records contained within the network record storage 210 and manage the encryption key storage 212. The encryption/decryption module 208 may also establish secure communications (e.g., via SSL and HTTPS) with a digital device when storing network credentials. This process is further described in FIG. 7. In accordance with some embodiments, the encryption/decryption module 208 may be optional.

The network record storage 210 and the encryption key storage 212 may store network records and encryption keys, respectively. The network record storage 210 and the encryption key storage 212 may comprise one or more databases. In one example, the network record storage 210 may store network records. A network record may comprise a DDID, SSID, and network credentials. The network record may also comprise a username and password for the user to access, alter, update, or store network records within the credential server 116.

In various embodiments, the network record may also allow multiple digital devices 102 to use the same network credentials. In one example, the user may own multiple digital devices 102. Multiple DDIDs, each DDID associated with a different digital device 102, may be included in the same network record. In some embodiments, multiple devices may be associated with one or more network records, and the one or more network records are associated with a user. As a result, the user may retrieve the network credentials for a hotspot using any number of digital devices 102. Those skilled in the art will appreciate that there are many ways in which the network records and/or the information contained therein may be stored and organized (e.g., different data structures, databases, records, organizing schemes, and/or methodologies).

FIG. 3 is a flow diagram of an exemplary process for providing network access to the digital device 102. When the digital device 102 first enters into a hotspot, the digital device 102 may scan for the local area network 106 in step 300. As a result of the scan, the network device 104 may provide network configuration information in step 302. The network configuration information may comprise one or more IP addresses for access to the DNS server 110.

In step 304, a credential request is generated by the digital device 102. Subsequently, the credential request may be sent to the DNS server 110 in step 306 using one of the IP addresses previously received from the network device 104.

Based on the credential request, the credential server 116 is identified by the DNS server 110 in step 308. In other embodiments, the DNS server 110 forwards the credential request to the credential server 116. When the DNS server 110 is unable to locally resolve the DNS request, the credential request is forwarded to another DNS server on the communication network 114 (e.g., over port 53) which may then forward the credential request to the credential server 116. The credential request is forwarded, either directly or indirectly through one or more other DNS servers on the communication network 114, to the credential server 116 in step 310.

The credential server 116 identifies the network credential needed based on the credential request in step 312. For example, the credential request may comprise an identifier (i.e., the DDID) for the digital device 102 as well as an identifier for the hotspot SSID (e.g., the service provider such as an operator). The identifiers may be compared against a table (e.g., network record) of such identifiers by the credential request module 204 or the credential request response module 206 to determine the proper network credential. A credential request response is then generated by the credential request response module 206 in step 314 and relayed back to the DNS server 110 in step 316. The DNS server 110 forwards the credential request response back to the digital device in step 318.

The digital device 102 may then retrieve the network credentials from the credential request response in step 320. The network credential may then be provided to the network device 104 in step 322. Upon verifying the network credentials, the network device 104 provides network access to the digital device 102 in step 324.

Referring now to FIG. 4, an exemplary credential request 400 is shown in more detail. According to exemplary embodiments, the credential request module 204 may generate the credential request 400. In one embodiment, the credential request 400 may be a DNS string having a structure that comprises a location identifier 402, a sequence identifier 404, a signature 406, the DDID 408, a service set identifier (SSID) 410, and a version identifier 412.

The optional location identifier 402 may indicate a physical or geographic location of the digital device 102, the network device 104, the authentication server 108, or the access controller 112. In various embodiments, the location identifier 402 may be used by the credential server 116 to track the usage of hotspots, users of the digital device 102, as well as the digital device 102.

The sequence identifier 404 may comprise any number or set of numbers used to correspond to a subsequent request to the credential server 116 to determine if the login is successful. That is, the sequence identifier 404 provides a correlation mechanism by which verification of the login process may be made by the credential server 116.

In exemplary embodiments, the signature 406 comprises a cryptographic signature (i.e., digital signature) that is utilized to prevent spoofing. The signature 406 of the request from digital device 102 is verified by the credential server 116. If the signature 406 is not valid, then the request is rejected by the credential server 116.

The DDID 408 comprises an identifier of the digital device 102. For example, the DDID 408 may comprise a MAC address or any other identifier of the digital device 102.

The SSID 410 comprises an identifier of the network access point or Wi-Fi service provider. For example, the SSID 410 may comprise the name of the service provider or the name of the venue operating the network device 104.

The version identifier 412 may identify the protocol or format of the credential request 400. For example, a digital device 102 may generate the credential request 400 and organize the data in a number of different formats. Each different format may be associated with a different version identifier. In some embodiments, the components of the credential request response module 206 may be updated, reconfigured, or altered over time, which may affect the structure of the credential request 400. As a result, the credential server 116 may receive a plurality of credential requests 400 which are formatted differently. The credential server 116 may access the required information from each credential request based on the respective version identifier.

FIG. 5 is a block diagram of an exemplary credential request response. According to exemplary embodiments, the credential request response module 206 may generate the credential request response 500. In one embodiment, the credential request response 500 may comprise encrypted text 502. The encrypted text may comprise an optional nonce 504 and credential information 506. The credential information may comprise key/value pairs 508 through 510.

As previously discussed, the credential request response may be formatted as a DNS response comprising encrypted text 502. The encrypted text 502 includes the network credentials (e.g., username, password, and login procedure information). Although the credential request response 500 is depicted as including encrypted text 502, the text within the credential request response 500 need not be encrypted.

The encrypted text 502 may comprise the nonce. The nonce, as previously discussed, may be retrieved from the credential request. Once the credential request response 500 is received by the digital device 102, the digital device 102 may compare the nonce within the credential request response 500 to the nonce transmitted within the credential request for authentication. Although the nonce is depicted as within the credential request response 500 in FIG. 5, the nonce is optional.

The credential information 506 may comprise a username, password, login procedure information, or a combination of these. The credential information 506 may comprise key/value pairs 508 through 510. Any number of key/value pairs may be within the credential information 506. The key/value pairs may represent the credential information to be received and translated by the digital device 102. The credential information 506 is depicted as key/value pairs for exemplary purposes only; the credential information may be within any format not necessarily limited to key/value pairs.

FIG. 6 is a flow diagram of the exemplary method for providing network credentials. In step 602, the credential server 116 receives the credential request from the digital device 102.

In various embodiments, the credential server 116 decrypts and authenticates the digital signature with an encryption key. The credential server 116 may then identify a network record based on the DDID and the SSID contained within the network record in step 604. In one example, the credential request response module 206 retrieves one or more network records associated with the DDID within the credential request. The credential request response module 206 then identifies at least one network credential associated with the SSID within the retrieved network record(s).

In step 606, the credential request response module 206 retrieves the identified network credential(s) from the selected network record. In one example, the credential request response module 206 identifies a username and password that the user of the digital device 102 must provide to the authentication server 108 to obtain network access. The credential request response module 206 generates the credential request response comprising the network credentials (e.g., username, password) to the digital device 102 in step 608.

In some embodiments, the credential request response module 206 may identify login procedural information as part of the network credentials. The credential request response module 206 may retrieve the login procedural information from the network record (e.g., the same network record containing a password associated with the SSID). The login procedural information may contain a form identifier and instructions (e.g., parameters) for the digital device 102 to follow to obtain network access. In one example, the digital device 102 retrieves the form identifier and instructions from the network credential within the credential request response. The digital device 102 may identify forms received from the authentication server 108 and input data based on the form identifier and instructions. In another example, the digital device 102 provides information to the authentication server 108 to obtain network access based on the login procedural information included within the credential request response. The process of providing information to the authentication server 108 is further described in U.S. patent application Ser. No. 11/899,638 entitled “Systems and Methods for Obtaining Network Access”, filed Sep. 6, 2007.

FIG. 7 is another flow diagram of the exemplary method for providing network credentials. The digital device 102 may search and find an available wireless network via the network device 104. While connecting to the hotspot, the digital device 102 may receive network configuration information in step 702. Network configuration information may comprise an identifier for the network device 104, or the DNS server 110. In one example, the digital device 102 receives a DNS server IP address (e.g., for the DNS server 110) during the connection process.

In step 704, the digital device 102 generates the credential request. The credential request may comprise a sequence identifier, DDID, and SSID. In step 706, the digital device 102 optionally generates a nonce and digitally signs the credential request with an encryption key. The digital device 102 transmits the credential request as a standard protocol in step 708. The network device 104 may receive and forward the credential request to the communication network 114. In various embodiments, the network device 104 may provide the credential request to the DNS server 110 which may forward the credential request to the credential server 116.

In exemplary embodiments, the credential request module 204 of the credential server 116 receives the credential request. The credential request module 204 may retrieve an encryption key associated with the DDID within the credential server from the encryption key storage 212. The credential request module 204 may then decrypt the digital signature of the credential request for authentication. The credential request module 204 may further retrieve the nonce and a sequence identifier from the credential request.

The credential request response module 206 of the credential server 116 may then retrieve a network record associated with the DDID and the SSID from the network record storage 210. The credential request response module 206 retrieves network credentials from the network record and generates the credential request response. The credential request response may comprise the network credentials and the nonce. The encryption/decryption module 208 may encrypt the credential request response with an encryption key associated with the DDID retrieved from the encryption key storage 212. In some embodiments, the credential request response is formatted as a standard protocol (e.g., DNS).

In step 710, the digital device 102 receives the credential request response. The digital device 102 subsequently authenticates the credential request response in step 712. In one example, the digital device 102 decrypts the credential request response with the same encryption key used to digitally sign the credential request. The digital device 102 may further retrieve the nonce within the credential request response and compare the nonce to the nonce transmitted within the credential request for further authentication. If the credential request response is found to be authentic, the digital device 102 retrieves the network credentials from the credential request response in step 714.

In step 716, the digital device 102 identifies the authentication requirements associated with network access. In various embodiments, the digital device 102 determines the correct information and network credentials to provide to the authentication server 108. In one example, the digital device 102 retrieves one or more network access pages from the authentication server 108. The digital device 102 may access the correct network access page from the authentication server and automatically make selections. In one example, the digital device 102 may automatically activate selections (e.g., activate buttons within the network access page, check boxes, and select radio buttons).

For example, the credential request response module 206 may provide instructions to the digital device 102 for the automatic selections within a network access page. As discussed herein, a network access page may comprise one or more web pages, one or more tags, or a combination of both retrieved from the authentication server 108. In one example, software within the digital device 102 may automatically check all selection boxes within a network access page. The digital device 102 may then uncheck select boxes based on the login procedure information. Those skilled in the art will appreciate that there may be many methods with which selections may automatically be made. In other embodiments, the digital device 102 receives XML tags from the authentication server 108. The digital device 102 may provide information based on the XML tags and instructions within the login procedural information to the authentication server 108 to obtain network access.

In step 718, the digital device 102 provides the network credential to the network device 104 to obtain network access to the communication network 114. In one example, the credential request response module 206 retrieves one or more forms from the authentication server 108, populates the forms with one or more network credentials, and provides the completed forms to the authentication server 108. In another example, the credential request response module 206 provides the network credentials as needed to the authentication server 108. Once the network credentials are received by the authentication server 108, the authentication server 108 may allow communication between the digital device 102 and the communication network 114. In one example, the authentication server 108 commands the access controller 112 to allow the digital device 102 access to the communication network 114.

The digital device 102 may subsequently test network connectivity to confirm network access. In one example, the digital device 102 transmits a request to the credential server 116 to determine if the communication network 114 is available. In some embodiments, the query or command contains the sequence identifier previously submitted within the credential request. If network access is successful, the credential server 116 may receive the request and retrieve the sequence identifier. The credential server 116 may then confirm that network access was successful.

FIG. 8 is a flow diagram of an exemplary method for receiving and storing network credentials. In various embodiments, users may create and store network records within the credential server 116. For example, the credential server 116 may comprise a credential storage module (not depicted) that provides a graphical user interface (GUI) that allows users to create, store, update, remove, and modify network records.

In step 802, the credential server 116 provides the user with a network credential request form. In one example, the credential server 116 provides the network credential request form to a user as one or more web pages over the Internet. The network credential request form is configured to receive the service provider's name (e.g., operator's name) and/or SSID and network credentials.

The service provider's name may comprise the name of the entity that operates the hotspot, one or more components related to the hotspot (e.g., the network device 104), or the infrastructure of the local area network 106. In some embodiments, the service provider's name comprises the name of an organization that manages one or more hotspots for another service provider. In one example, a coffee shop and bookstore may both use a third-party manager to manage the hotspots, even if the hotspots have different service providers. In some embodiments, the network credential request form may be configured to receive the third-party manager's name. In some embodiments, the service provider's name comprises the name of an organization that resells access to a hotspot network (e.g., an aggregator).

The network credential request form may also receive the SSID as a network service selection. In one example, the network credential request form comprises a pull down menu of different service providers and/or hotspots that the user may select. For example, a user may select “Starbucks” or “San Francisco International Airport” as a hotspot. The user may be given further options to such as geographic locations of the hotspot. The user may also select the service provider. For example, the user may select “T-Mobile” as a service provider. The network credential request form may then allow the user to select among one or more various hotspots associated with T-mobile. The selection(s) may then be stored as a network record. Alternately, a network service identifier associated with the selection(s) is generated as the SSID.

Further, the network credential request form may receive the network credential from the user. For example, the user may enter a username, password, passcode as network credentials within the network credential request form. In some embodiments, after the network credential request form receives the SSID, the network credential request form determines the type of network credentials required. For example, the network credential request form identifies the information required to access a network at a hotspot at the San Francisco International Airport previously selected by the user. The network credential request form then generates fields or selections to allow the user to enter only the information necessary (e.g., username, password) to obtain network access at the hotspot.

The credential server 116 may also require the user to register prior to receiving the network credential request form. During registration, the user may be required to agree to terms of service and enter customer information. Customer information comprises a username and a password to access the credential server 116 to store network credentials. Optionally, the customer information may comprise the user's address, contact information, and payment options for the user to use services offered by the credential server 116.

In step 804, the credential server 116 receives the customer information and network service selections over the network credential request form. In step 806, the credential server may retrieve the network credential. In step 808 the credential server 116 receives the customer information. The credential server 116 associates the network credential with the customer information, network service selection and network credential(s) in step 810 to create a network record. The network record is then stored in step 812.

In some embodiments, the user may manually access the credential server 116 via the Internet. In other embodiments, the user may download and install network credential software on the digital device 102. The network credential software may identify and send the DDID of the digital device 102 to the credential server 116. In other embodiments, the network credential software may be pre-installed on the digital device 102. When the digital device 102 first activates the network credential software, the network credential software may identify and send the DDID of the digital device 102 to the credential server.

The user may input the SSID (e.g., identify the service provider or hotspots) into the network credential software. The user may also input the network credentials within the network credential software. After the network credential software has obtained the DDID, SSID, and network credentials, the network credential software may upload the information to the credential server 116 which stores the information within a network record. In various embodiments, the network credential software may be downloaded from the credential server 116.

FIG. 9 is a block diagram of an exemplary digital device. The credential server 116 comprises a processor 900, a memory system 902, a storage system 904, an I/O interface 906, a communication network interface 908, and a display interface 910. The processor 900 is configured to execute executable instructions (e.g., programs). In some embodiments, the processor 900 comprises circuitry or any processor capable of processing the executable instructions.

The memory system 902 is any memory configured to store data. Some examples of the memory system 902 are storage devices, such as RAM or ROM. The memory system 902 can comprise the ram cache. In various embodiments, data is stored within the memory system 902. The data within the memory system 902 may be cleared or ultimately transferred to the storage system 904.

The storage system 904 is any storage configured to retrieve and store data. Some examples of the storage system 904 are flash drives, hard drives, optical drives, and/or magnetic tape. In some embodiments, the credential server 116 includes a memory system 902 in the form of RAM and a storage system 904 in the form of flash data. Both the memory system 902 and the storage system 904 comprise computer readable media which may store instructions or programs that are executable by a computer processor including the processor 900.

The optional input/output (I/O) interface 906 is any device that receives input from the user and output data. The optional display interface 910 is any device that is configured to output graphics and data to a display. In one example, the display interface 910 is a graphics adapter. It will be appreciated that not all digital devices 102 comprise either the I/O interface 906 or the display interface 910.

The communication network interface (com. network interface) 908 can be coupled to a network (e.g., the local area network 106 and communication network 114) via the link 912. The communication network interface 908 may support communication over an Ethernet connection, a serial connection, a parallel connection, or an ATA connection, for example. The communication network interface 908 may also support wireless communication (e.g., 802.11 a/b/g/n, WiMax). It will be apparent to those skilled in the art that the communication network interface 908 can support many wired and wireless standards.

In various embodiments, systems and methods are described that enable a digital device to automatically select and access an available wireless network from a plurality of available wireless networks based on rules to achieve a satisfactory quality of service. Such rules could be implemented in the digital device itself, on a server in communication with the digital device, or a combination of both. In various embodiments, a wireless network is a network that allows wireless access between a digital device and a communication network such as the Internet.

In accordance with some embodiments, a user of a wireless digital device (e.g., digital device capable of Wi-Fi communication) creates an account on a web server and registers one or more digital devices (e.g., computers, laptops, personal digital assistants, and cell phones) with that account. The registered digital devices can be managed and a network record provisioned by a central server (e.g., a profile server or a credential server) via a network communication mechanism, such as HTTP.

FIG. 10 is a diagram of another environment in which embodiments of the present invention may be practiced. In various embodiments, a user with a digital device 1002 enters an area located near the network devices 1004 and 1006. In one example, the network devices 1004 and 1006 are separate access points which may each be used to establish communication between the digital device 1002 and the communication network 1008.

The digital device 1002 may scan the area surrounding the digital device 1002, detect the two network devices 1004 and 1006, and generate a list of available wireless networks with which the digital device 1002 may establish communication. In some embodiments, the list of available wireless networks comprises DDID, SSID, and/or BSID identifiers of the network devices 1004 and 1006.

Subsequently, the digital device 1002 provides the list of available wireless networks to a rules server 1010. In one example, the digital device 1002 provides the list of available wireless networks as a standard protocol over an open port of either the network device 1004 or the network device 1006 to the communication network 1008 and, ultimately, to the rules server 1010. In another example, the digital device 1002 provides the list of available wireless networks over another network such as a cellular communication network (e.g., via CDMA, GSM, 3G, or EVDO) or other wireless network (e.g., Wi-Fi, Wimax, or LTE network) not depicted.

The rules server 1010 receives the list of available wireless networks and may retrieve a network profile for each wireless network identified within the list. A network profile is a record that is associated with a wireless network and comprises attributes concerning performance and/or quality of service provided by the associated network. In one example, the rules server 1010 identifies each network within the list and provides the SSID and/or BSID for each network to the profile server 1014. The profile server 1014 may then provide a network profile (based on the SSID and/or BSID) for each network to the rules server 1010. In some embodiments, the profile server 1014 retrieves the network profile from a database or other server (e.g., network database server 1012).

The rules server 1010 may select a preferred wireless network from the list of available wireless networks based on attributes within the network profiles and/or any attributes received from the digital device 1002. An attribute is a characteristic of a wireless network. In various embodiments, an attribute includes a performance metric, a shared indicator, or a service identifier. A performance metric of a wireless network is any measure of network performance. In some examples, a performance metric may comprise a latency metric, a bandwidth metric, or a quality of service (QOS) metric. Those skilled in the art will appreciate that a performance metric may include any type of metric that represents performance of a wireless network.

A latency metric is a measurement that represents time to send a packet of data from the digital device to a server on a network. In some embodiments, the digital device 1002 may send an ICMP “echo request” packet to a server and listen for an ICMP “echo response” reply. The latency metric may comprise an estimate of the round-trip time (generally in milliseconds) and/or include any packet loss. In another example, the latency metric is half of the estimated round-trip time.

A bandwidth metric is a measurement of the available bandwidth of a wireless network. In one example, the digital device may test available bandwidth by sending a block of data over the wireless network to a server and timing the response.

A QOS metric is any metric that measures the quality of service of the wireless network, the access device 1004, the access device 1006, and/or the communication network 1008. In one example, the QOS metric represents a reliability of the DHCP which is determined by timing the length of time required to get an IP address. The reliability of the DHCP may comprise a statistical measurement, a probability of receiving an IP address at all, and/or a distribution of time.

A shared indicator indicates if a wireless network is shared. In some embodiments, the shared indicator may be one of three states including “shared,” “not shared,” and “unknown”. Although the shared indicator may only include a single state (e.g., “not shared”), those skilled in the art will appreciate that the shared indicator can have any number of states. A wireless network with a shared indicator that indicates that the network is “shared” may indicate that the owner of the wireless network intends for others to use the network. One example of a “shared” network may include a wireless network which is intentionally “open” (e.g., unencrypted) for others to use.

A wireless network with a shared indicator that indicates that the network is “not shared” may indicate that the owner of the wireless network does not desire anyone who does not have express permission to access the network. In one example, wireless networks that are not shared are often intentionally encrypted (e.g., through WEP or WPA) so as to limit access to unauthorized users. Not all networks that are “not shared,” however, are encrypted. For example, the owner of the network may misconfigure the network device or, through error, allows a network to be open (i.e., unencrypted) even though the network is not intended to be shared.

A wireless network with a shared indicator that indicates that the network is “unknown” may indicate that the wireless network may either be “shared” or “not shared.” For example, the intent of the owner of an open network may not be known.

A service identifier may identify one or more services supported by the wireless network. In one example, one or more service identifiers indicate that a wireless network supports VOIP, teleconferencing, and/or video conferencing. The service identifier may identify any kind of service supported by the wireless network. In some embodiments, the service identifier may identify services that are not supported by the wireless network.

Those skilled in the art will appreciate that the network profile may comprise any number of attributes. Further, those skilled in the art will appreciate that the network profile may comprise only one or more performance metrics, only one shared indicator, or only one or more service identifiers.

In various embodiments, the rules server 1010 selects one or more wireless networks from the list of available wireless networks based on the attribute analysis. In one example, the rules server 1010 applies rules to the attributes. The rules may comprise minimum requirements, personalized settings, and attribute comparisons. In one example, the rules applied by the rules server 1010 may compare the attributes of one or more wireless networks to one or more minimum requirements. If the attributes for a wireless network are below the minimum requirements, then the wireless network may not be selected or removed from the list of available wireless networks.

In some embodiments, the rules applied by the rules server 1010 may be based on personalized settings by the user. For example, the user of the digital device 1002 may indicate personalized settings that indicate that the digital device 1002 is only to connect over wireless networks that have been designated as “shared.” In this example, the rules server 1010 may select only those wireless networks with an attribute that comprises a shared indicator that identifies the wireless network as “shared.”

In various embodiments, the rules applied by the rules server 1010 may be based on a comparison of the attributes of one wireless network to another. In one example, the attributes may indicate that one wireless network has a greater bandwidth and shorter latency than another. In this example, the rules server 1010 may select one wireless network that has better performance or valuable services in comparison to another. Those skilled in the art will appreciate that there may be any kind of rule used to select or to assist in the selection of a wireless network from the list of available wireless networks.

More than one rule may be applied by the rules server 1010 in making the wireless network selection. In one example, the rules server 1010 may apply personalized settings of the user before comparing attributes from different wireless networks and making a selection. In another example, the rules server 1010 may apply minimum requirements to the attributes before comparing the attributes.

Once the rules server 1010 selects the wireless network based on the comparison of attributes from the network profiles, the rules server 1010 may provide the wireless network selection to the digital device 1002. A wireless network selection includes one or more identifiers (e.g., network identifiers) that identify at least one wireless network. The wireless network selection may identify a single wireless network or comprise a sorted list of wireless networks which is sorted in order of preference.

In some embodiments, the rules server 1010 provides credentials (e.g., a credential request response) for the selected wireless network in addition to the wireless network selection to the digital device 1002. In one example, the rules server 1010 provides the selected wireless network to the credential server 1016 which then provides a credential request response (even though no credential request has been made) for the selected wireless network to the digital device 1002. In other embodiments, the digital device 1002 receives the wireless network selection and then proceeds to transmit a credential request to the credential server 1016 to receive the credentials as discussed herein.

Further, in various embodiments, the digital device 1002 attempts to establish a connection based the selected wireless network. If the connection fails, the digital device 1002 may transmit a credential request to the credential server 1016 to retrieve credentials for network access as described herein. The digital device 1002 may provide the credential request to the credential server 1016 over an open port of the network device 1004. In another example, the digital device 1002 may provide a credential request over any other network including a connection with a different network device or over a cellular connection.

Although the rules server 1010, network database server 1012, profile server 1014, the credential server 1016, and the web server 1018 are depicted as separate servers in FIG. 1, the servers may all be combined as one or more servers. Similarly, the functions of any of the servers may be performed by one of the other servers depicted or any other server.

Although FIG. 10 depicts multiple servers (e.g., rules server, network database server, profile server, credential server, and web server) for performing the selection of a wireless network from the plurality of available wireless networks, it will be appreciated by those skilled in the art that the selection of the wireless networks may occur within the digital device 1002. In one example, the digital device 1002 retrieves the scan results listing available wireless networks and selects a wireless network based on configuration preferences. The configuration preferences may be based on one or more locally executed rules, preferred signal strength, or any other attribute or attributes. In another example, the digital device 1002 selects a wireless network that supports a desired service (e.g., VOIP), meets a minimum latency standard, and meets a minimum QOS standard. In another example, the profile server 1014 provides the desired network profiles to the digital device 1002 which performs the analysis to determine the preferred wireless network.

FIG. 11 is a flow diagram of an exemplary process for providing a selection of a wireless network. In step 1102, a server (e.g., rules server 1010, network database server 1012, profile server 1014, credential server 1016, or web server 1018) receives a list of available wireless networks from the digital device 1002. In some examples, the list comprises the SSIDs or BSIDs of one or more network devices (e.g., network device 1004 and network device 1006). The list can comprise any information that identifies a network and/or network device.

In some embodiments, the server also receives one or more attributes associated with a network and/or network device. In various embodiments, the digital device 1002 measures signal strength, determines available services, or takes a performance metric for one or more networks and/or network devices that are identified on the list of available wireless networks.

In step 1104, the server retrieves a network profile from a plurality of network profiles stored in a network database for each available wireless network on the list of available wireless networks. Each network profile may comprise at least one attribute. In some embodiments, not all wireless networks on the list have a network profile. When a network profile for a wireless network on this list is not found, a network profile associated with the wireless network may be then created. If attributes are received from the digital device 1002, the server may determine which attribute received from the digital device 1002 is associated with which network, network device, and/or network profile.

In step 1106, the server compares attributes from each network profile against minimum requirements. In one example, the server compares latency metrics from all network profiles in the list (if available) against a minimum latency metric. The server may also compare attributes received from the digital device 1002 against the minimum requirements. In step 1108, the server removes one or more wireless networks from the list of available wireless networks and/or wireless network profiles based on the comparison(s). For example, any wireless network with a latency metric that falls below the minimum latency metric may not be selected. In other embodiments, a wireless network with a latency metric that falls below the minimum latency metric may receive a weighted value that will be compared to other wireless networks to assist in the selection process.

In some embodiments, the user of the digital device 1010 determines the minimum requirements. In other embodiments, the minimum requirements may be selected for the user (e.g., by an administrator).

In step 1110, the server retrieves personalized settings for a user. The personalized settings may be sent by the user to the server. In some embodiments, the user has an account with the web server 1018 which contains the personalized settings. In one example, the server receives a user identifier along with the list of available wireless networks. The server then accesses the user's account and receives the personalized settings which are then applied to the attributes of the network profiles associated with a wireless network on the list. In various embodiments, users may configure personalized settings (e.g., the “aggressiveness”) at which a digital device 1002 may connect to a wireless network. Such configurations could include:

-   -   (a) Connect to anything open regardless of shared indicator;     -   (b) connect to anything open except those with default         manufacturer SSIDs (e.g., “linksys”) that likely indicate the         owner simply left the access point open out of the box and is         unaware how to configure security functions;     -   (c) connect to anything open that the profile server 108 has         seen (or stored information regarding the Wi-Fi network); or     -   (d) connect to anything open with a shared indicator of         “shared,” or has been marked as shared by some other means.         Those skilled in the art will appreciate that there may be many         personalized settings.

In step 1112, the server removes one or more wireless networks from the list or network profiles based on the personalized settings. For example, the personalized settings may indicate that the user only wishes to connect to wireless networks that support videoconferencing and maintain a user defined QOS requirement. The server may then remove any wireless networks from the list of available wireless networks based on the attributes either from the network profiles or recently received from the digital device 1002 that do not meet the user's personalized settings.

In some embodiments, the personalized settings may then be taken into account either before or after comparison of attributes from the network profiles. In one example, personalized settings indicate that the user does not wish to connect to a wireless network that is not designated as “shared” or providing certain services. In one example, the rules server 1010 either does not retrieve the network profiles associated with networks that do not provide the necessary service and/or does not compare attributes associated with those networks. In other embodiments, the digital device 1002 applies personalized settings to results (e.g., the wireless network selection) received from the rules server 1010 before accessing a preferred wireless network.

In step 1114, the server compares the attributes of the remaining wireless networks on the list. In various embodiments, the server will apply a weight and normalize one or more of the attributes (e.g., metrics) from within the network profiles. In some embodiments, older attributes may be removed or weighed less than other attributes that are newer. In one example, any metric that is over one week old may receive less weight than a similar newer metric. In another example, a metric that is over one month old may be removed from the network profiles or not considered in the comparison. Those skilled in the art will appreciate that not all attributes or information from within the network profiles may be taken into account in the comparison.

Each network profile may comprise any number of attributes. In one example, the rules server 1010 makes a wireless network selection based on comparing a metric from two different network profiles. In some embodiments, the rules server 1010 selects a wireless network based on a comparison between two similar metrics (i.e., the latency metric from the first network profile is compared to the latency metric from the second network profile). Those skilled in the art will appreciate that the rules server 1010 may select a wireless network based on comparisons between two similar recently received metrics or a recently received metric and another within a network profile.

In other embodiments, the rules server 1010 selects a wireless network based on a comparison of two dissimilar metrics (i.e., the latency metric from the first network profile is compared to a bandwidth metric from the second network profile). The rules server 1010 may execute an algorithm to weigh and normalize similar and/or dissimilar metrics or attributes in order to make a comparison for selecting the appropriate wireless network. In one example, the rules server 1010 compares a latency metric in the first network profile to a bandwidth metric in the second network profile. The rules server 1010 may execute an algorithm to weigh and normalize the metrics. The algorithm may weigh the latency metric more than the bandwidth metric since latency may have a greater impact on network performance.

An attribute or metric may receive different weights depending on any number of factors. For example, a latency metric may receive a given weight when the metric falls within an acceptable range, otherwise the latency metric may be significantly less weight. A metric recently received from the digital device 1002 may receive greater weight than a metric of a similar type within a network profile. Those skilled in the art will appreciate that there are many ways to compare similar and/or dissimilar performance and/or qualitative metrics.

In step 1116, the server selects a wireless network based on the comparison of attributes. The wireless network selection may comprise a single preferred wireless network or a list of wireless networks sorted in order of preference. In one example, the rules server 1010 identifies the most preferred network, the second most preferred network, and so on. The rules server 1010 then provides the wireless network selection to the digital device 1002 in step 1118.

In various embodiments, the rules server 1010 only compares metrics that are recently received from the digital device 1002. In one example, two latency metrics are received from the digital device 1002. Each latency metric is associated with a separate wireless network identified on a list of available networks. In this example, the rules server 1010 may select a wireless network based on a comparison of the two attributes.

FIG. 12 is a flow diagram of an exemplary process for selecting a wireless network. In step 1002, the digital device 1002 enters into an area with two wireless networks and the digital device 1202 scans for networks to access. In step 1204, the digital device 1002 receives a first and a second network identifier of available wireless networks. As discussed herein, the first and second network identifiers may comprise BSIDs, SSIDs, or any other network identifiers. For example, the first network identifier may comprise a BSID and the second network identifier may comprise an SSID identifier. In another example, the first network may provide multiple identifiers including a BSID and an SSID while the second network provides only an SSID. In this example, the first network identifier may comprise both the BSID and the SSID of the first network device while the second network identifier is only an SSID of the second network device.

In step 1206, the digital device 1002 generates a list of available wireless networks. For example, the digital device 1002 may generate a list comprising the first network identifier and the second network identifier. The list is then provided to a server in step 1208.

In step 1210, the digital device 1002 receives a wireless network selection from the server. The wireless network selection may comprise an identifier that identifies the selected wireless network or identifies the network device associated with the selected wireless network (e.g., a BSID and/or SSID of the network device). In various embodiments, the wireless network selection may comprise a list of wireless networks sorted by preference. The list may comprise two or more identifiers that identifies a selected wireless network or network device.

In step 1212, the digital device 1002 receives credentials for the wireless network selection from the server. In some embodiments, the credentials are received from the same server that received the list of available wireless networks from the digital device 1002.

In various embodiments, the digital device 1002 receives the wireless network selection from the server and then provides a credential request to receive the credentials for the desired network. In one example, the digital device 1002 provides the credential request in the same manner that the digital device 1002 provided the list of available wireless networks (e.g., over an open port of a network). In some embodiments, the preferred network does not require credentials or the credentials are stored locally on the digital device 1002.

In step 1214, the digital device 1002 accesses the selected wireless network with the credentials. The process of applying the credentials to a login page or the like is discussed herein.

In various embodiments, the digital device 1002 may provide the list of available wireless networks to the server over an open port of a network device in a manner similar to providing a credential request discussed herein. In other embodiments, the digital device 1002 may provide the list to the server over another network. In one example, the digital device 1002 generates a list of available Wi-Fi networks and provides the list over a cellular network (e.g., EVDO or 3G network). In this example, the wireless network selection may be returned to the digital device over the cellular network and then the digital device 1002 may attempt to access the preferred Wi-Fi network.

In another example, the digital device 1002 accesses one wireless network. The digital device 1002 can then provide a list of the available wireless networks to the server. The server may return the wireless network selection to the digital device 1002. If the preferred wireless network is not the network that the digital device 1002 has originally accessed, then the digital device 1002 may drop the connection and access the preferred wireless network.

Although FIGS. 10-12 contemplate a server receiving a list of available wireless networks, determining a wireless network selection, and providing the selection to the digital device 1002, those skilled in the art will appreciate that a server is not necessary. In one example, the digital device 1002 generates a list of available wireless networks and then retrieves any available information regarding the networks on the list (e.g., from locally stored network profiles, from one or more network devices, from a local or remote database, and/or retrieving information from another network such as the Internet). The digital device 1002 may then make comparisons based on what attributes associated with the networks are available to make a selection or generate a prioritized list. The digital device 1002 may then access the selected wireless network.

In various embodiments, the digital device 1002 may generate and provide attributes regarding one or more networks to update the network profiles. In one example, the digital device 1002 determines the quality of the signal, bandwidth, or any other metrics and provides those metrics along with the list of available wireless networks to a server. In another example, as the digital device 1002 accesses a selected wireless network, measures attributes, and provides the attributes update metrics within a network profile. Attributes (e.g., latency metrics, bandwidth metrics, and QOS metrics) may be taken by the digital device 1002 at any time and used to update the network profiles.

FIG. 13 is a diagram for selecting a wireless network and accessing the selected wireless network. In various embodiments, the network device 1004 and network device 1006 provide a first and second network identifiers to the digital device 1002 in steps 1302 and 1304. In step 1306, the digital device 1002 generates metrics (i.e., attributes) by taking measurements regarding wireless networks associated with the network device 1004 and network device 1006. In some examples, the metrics may include latency, strength of signal, or QOS metric.

In step 1308, the digital device 1002 generates a list of available wireless networks which may include the network identifier from the network device 1004 as well as the network identifier from the network device 1006. In some embodiments, the digital device 1002 may also comprise personalized settings which may indicate a preference between the two network identifiers or eliminate one or both of the network identifiers. In one example, the personalized settings indicate that only open networks that do not have a default manufacturer SSID (e.g., “linksys”) may be accessed. In this example, if the network identifier from the network device 1004 indicates a default manufacturer SSID, the digital device 1002 may not include that network identifier for the network device 1004 in the list of available wireless networks.

In some embodiments, if the digital device 1002 cannot generate a list identifying at least two or more networks, the digital device 1002 does not send the list. In one example, if the digital device 1002 can only identify one available wireless network that meets the user's requirements, then the digital device 1002 may attempt to access the wireless network directly or send a credential request for to a server to retrieve any necessary credentials for access.

In step 1310, the digital device 1002 provides the attributes and the list of available wireless networks over an open port (e.g., port 53) of the network device 1006 which acts like a proxy in providing the attributes and list of available networks to the rules server 1010. In other embodiments, the digital device 1002 provides the attributes and the list over an open port of the network device 1004. Alternately, the digital device 1002 may provide the attributes and the list over separate networks (e.g., the attributes over an open port of one of the network devices and the list over a cellular network). In step 1312, the network device 1006 acts as a proxy by providing the attributes and list via DNS to the rules server 1010.

In step 1314, the rules server 1010 retrieves network profiles. In one example, the rules server 1010 retrieves the network identifiers from the list and retrieves network profiles associated with the network identifiers.

In step 1316, the rules server 1010 (or profile server 1014) updates attributes within the network profiles with the attributes received from the digital device 1002. In one example, a new latency metric from the digital device 1002 is used to update the network profile associated with the network identifier from the network device 1004. A time-to-live value associated with the attribute may also be updated to indicate that the new latency metric is recent.

In step 1318, the rules server 1010 selects a network device based on comparing the attributes from within the network profiles. In some embodiments, the rules server 1010 also applies personalized settings from the digital device 1002 or from an account associated with the digital device 1002 (e.g., via the web server 1018) before making a selection. The rules server 1010 may prepare a prioritized list of the two network devices from the list provided by the digital device 1002. The list is prioritized based on which of the two network devices provides the most desirable service based on the metrics from the network profiles.

In step 1320, the rules server 1010 provides the wireless network selection and credentials via DNS back to the network device 1006 to function as a proxy to send the information to the digital device 1002. In one example, the rules server 1010 selects the network device 1004. The rules server 1010 may retrieve credentials for the network device 1004 based on the network identifier of the network device 1004. For example, the rules server 1010 may provide a credential request to the credential server 1016. The credential server 1016 may provide a credential request response containing necessary credentials to the rules server 1010 which then sends both the credentials received from the credential server 1016 as well as the wireless network selection to the digital device 1002.

In step 1322, then network device 1006 provides the network selection and the credentials over the open port to the digital device 1002. In step 1324, the digital device 1002 provides the credentials to access the network device 1004 and generates additional attributes regarding the network (i.e., take additional measurements). Once a connection is established, the new attributes are provided to the rules server 1010 or profile server 1014 to update the network profile associated with the network device 1004 in step 1326. In one example, the digital device 1002 may measure the time required to establish the connection with the network device 1004. The time required to establish the connection may then be used to update attributes in a network profile. If a connection is not established or fails, that information may also be provided to update the associated network profile.

In some embodiments, if the network connection with the selected network fails, the digital device 1002 may re-attempt to make the connection. If multiple attempts to make the connection fail, information regarding the failure is sent to update the associated network profile. The digital device 1002 may then attempt to make a connection with another network device (e.g., the network device 1006). In some embodiments, the digital device 1002 re-scans the area, generates a new list of available networks which may not include the network that the digital device 1002 failed to connect. The new list may be sent to the rules server 1010 to receive a new wireless network selection and the process may repeat.

In some embodiments, the rules server 1010 provides a prioritized list of available wireless networks sorted by preference. In one example, the rules server 1010 provides a prioritized list of three networks to the digital device 1002. The digital device 1002 may then attempt to access the first wireless network on the prioritized list. If the digital device 1002 is unable to connect to the first wireless network, then the digital device 1002 may proceed to attempt to connect to the next network on the list. Those skilled in the art will appreciate that the prioritized list may contain all, one, or some of the wireless networks identified in the list of available wireless networks. For example, the rules server 1010 may not identify wireless networks which are known to provide poor performance, do not provide desired service (e.g., VOIP service), and/or are otherwise blacklisted.

In various embodiments, the user of the digital device 1002 may override the wireless network selection to access any wireless network. In one example, the user chooses the priority of available wireless networks. In some embodiments, the user may configure the digital device 1002 or configure an account with the web server 1018 to include personal preferences that may reorder or otherwise alter a prioritized list of wireless networks from the rules server 1010. For example, the list of available wireless networks may be altered based on user preferences by the digital device 1002 or the web server 1018 prior to being provided to the rules server 1010.

In some embodiments, in addition to one or more open Wi-Fi networks, there may also be one or more encrypted Wi-Fi networks in a given location. A digital device 1002 may connect to an open Wi-Fi network and transmit the SSID of other Wi-Fi networks, including encrypted Wi-Fi networks, to the rules server 1010 via a network communication protocol such as HTTP.

The rules server 1010 may then determine, based on personalized settings or other rules, that an available encrypted Wi-Fi network is the preferred choice for a network connection. The rules server 1010 may transmit the necessary encryption keys to the digital device 1002 over the current open Wi-Fi network connection and send instructions to the digital device 1002 to switch to the encrypted Wi-Fi network.

In various embodiments, a network database may be used to centralize information regarding many different networks. A network database may store a plurality of network profiles. Each network profile within the network database may be associated with a separate network. In some examples, the network profile is associated with a separate network by an BSID, DDID, SSID, or other identifier. Each network profile may comprise attributes from one or more users.

As more digital devices access new and existing wireless networks, attributes (e.g., metrics and other information) may be collected and stored within the network profiles of the network database. The attributes from many digital devices that access the same wireless network may be weighted and/or averaged to produce an attribute with a higher probability that the attribute will match expected future network performance. Further, users may contribute information or attributes directly (e.g., indicating that a network is shared) to more accurately characterize the wireless network.

As attributes associated with available wireless networks are gathered and organized, the quality of selections of wireless networks based on the attributes from the network database may increase. For example, a latency metric from a single user's experience with a wireless network may not be representative of the performance of the network. However, a latency metric that is formed from averaging the latency metrics received from twenty separate users who use the same wireless network may be a very accurate indicator of future performance. As more attributes and information is gathered on an increasing number of wireless networks and stored within the network database, the quality and service of wireless networks may be measured. As a result, a digital device may automatically access a wireless network and receive an expected or at least a minimum level of performance.

FIG. 14 is a flowchart of an exemplary process for updating and storing attributes associated with wireless networks within a network database. Digital devices may scan or receive attributes regarding different network devices and/or networks. These attributes may be provided to a network database where the information will be stored and aggregated with other attributes for the same network. The digital device may provide that attributes to the network database in many ways. For example, the digital device may provide the attributes to the network database over an open port of a network device. Alternately, the digital device may provide the attributes to the network database through a cellular network or any kind of network.

The digital device may provide attributes to the network database at any time. In one example, the digital device provides the attributes to the network database prior to logging into a wireless network (e.g., as a standard protocol over an open port). In another example, the digital device may transmit one or more attributes along with a list of available wireless networks as discussed in FIG. 13. Further, attributes may be collected by the digital device while using a wireless network. In one example, the digital device may be logged into a wireless network for two or more hours. During that time, the digital device may take a latency metric every ten minutes. Similarly, during that time, the digital device may take a bandwidth metric or measure a QOS metric. The attributes may be sent at any time to the network database which may analyze and/or store the attributes.

In step 1402, a digital device 1002 receives a network identifier and generates an attribute associated with the network identifier. In one example, the network identifier is a BSID of the wireless network. The attribute may comprise a performance metric, shared indicator, or service identifier. In one example, the digital device 1002 measures a bandwidth metric of a wireless network associated with the network identifier.

In step 1404, the digital device 1002 provides the network identifier and attribute to a server to store the attribute within the network database. The digital device 1002 may provide the attribute to the network database as the attribute becomes available. Alternatively, the digital device 1002 may provide one or more attributes to the network database at predetermined intervals or at a given time. Those skilled in the art will appreciate that the digital device 1002 may be configured by a user or an administrator to control how and when the digital device 1002 generates attributes or tests the network to generate one or more attributes. Further, the user or administrator may configure how and when the digital device 1002 provides the attributes to the network database.

The server may be any kind of server (e.g., a rules server 1010, network database server 1012, profile server 1014, credential server 1016, or web server 1018). In one example, the profile server 1014 receives the network identifier and attribute from the digital device 1002. The profile server 1014 may determine if a network profile associated with the network identifier is within the network database in step 1406. In one example, the profile server 1014 queries the network database server 1012 for a network profile associated with the network identifier. The network database server 1012 may control the network database.

If the network profile exists, then another user or administrator has identified or had experience with the wireless network associated with the network identifier. If the network profile does not exist, then the network database may not have previously received an attribute for the wireless network associated with the network identifier. If the network profile exists, the network profile is retrieved in step 1408. In one example, the network database server 1012 provides the requested network profile to the profile server 1014.

The profile server 1014 may then update an existing attribute already within the network profile with the newly received attribute in step 1410. In one example, a latency metric may already exist within the network profile. The older latency metric may be averaged with the new attribute to form a new latency metric that is then stored within the network profile. If an attribute of the same type as the received attribute does not already exist within the network profile, the attribute may be stored within the network profile. For example, the recently received attribute may be a service identifier that indicates that the network supports VOIP. If no such attribute exists within the network profile, the service identifier is then stored within the network profile.

Those skilled in the art will appreciate that attributes may be combined by any kind of algorithm. In various embodiments, each quantitative attribute (e.g., performance metric) may be weighted based on any number of factors. In one example, individual quantitative attributes for the same metric are all stored within a network profile. The profile server 1012 may execute an algorithm that weighs each individual quantitative attribute based on the number of individual attributes and/or when the attributes were received (older attributes are weighted less than newer attributes). As the number of attributes for each type is received, the accuracy of a weighted representation (e.g., an weighted average) may increase.

If the network database server 1012 finds that the network profile did not previously exist, the network database server 1012 or the profile server 1014 may create a new network profile associated with the network identifier. The profile server 1014 may then store the attribute within the network profile in step 1414.

In various embodiments, the digital device 1002 enters into an area with five wireless networks. The digital device 1002 may generate a list of available wireless networks comprising network device identifiers for all five networks. If any of the five networks have not been previously identified, the network database server 1012 (or any serve) may automatically create a new network profile for each network not previously identified.

In step 1416, the profile server 1012 optionally updates a time-to-live characteristic of the attribute. The time-to-live characteristic is a predetermined time that may affect the weight of the attribute in an algorithm and/or may be a deadline from which the attribute is considered expired. In one example, an attribute may be weighted less as the attribute get older (e.g., received two to three weeks before the current time). In some embodiments, when an attribute is thirty days old, the attribute is automatically expired. In one example, an expired attribute may be removed from the network profile automatically. In another example, the attribute may continue to exist in the network profile but is either ignored or weighted very lightly in comparison to newer or “fresher” attributes of the same type.

In some embodiments, a weighted average of all attributes of a certain type (e.g., the last twenty latency metrics associated with a single wireless network received over the last two weeks) is also associated with a time-to-live characteristic. If the average is not updated, the average itself may be weighted in a manner consistent with the stale attributes. In some embodiments, averages may expire based on the time-to-live characteristic if the average is not updated regularly.

In step 1418, the profile server 1014 or the network database server 1012 stores the network profile within the network database.

In another example metrics are provided by the digital device 1002 to update one or more network profiles. In one example, a wireless network is recently upgraded to support VOIP. In this example, the digital device 1002 may detect the new capability and provide a service identifier that indicates this capability to the rules server 1010. The rules server 1010 may retrieve and update a network profile from the profile server 1014 to indicate the new capability. The updated network profile may then be stored within the network database.

In various embodiments, attributes received from a digital device 1002 may be stored within a plurality of network profiles associated with different network device identifiers. In one example, an attribute comprises a physical location of the network and/or network device identifier. If the digital device 1002 provides a list of available wireless networks, and the location of one of the wireless networks is known, then the network database server 1012 may conclude that all networks on the list of available wireless networks must also be in the same general location. As a result, the network database server 1012 may create or update attributes in all network profiles associated with the list to specify a location even if one or more of those wireless networks are otherwise encrypted (e.g., WEP or WPA).

A server (e.g., the profile server 1014, the credential server 1016, or the web server 1018) may also be able to determine the location of the digital device 1002. In one example, the profile server 1014 receives a BSID from the digital device 1002. The profile server 1014 may refer to a database of locations for different BSIDs to determine the location of the user. In another example, the profile server 1014 may query a GPS unit in the digital device 1002 or a GPS unit within the network device associated with the network device identifier to receive location information. In yet another example, the location of the digital device 1002 may be determined by using an IP address of the digital device 1002. The location attribute for all wireless networks in the area may then be updated to indicate the general location of related wireless networks or network devices.

In some embodiments, the location of the user may be determined or retrieved from a network profile in order to identify the general physical location of the user. The general physical location of the user can be used to update attributes of networks in the user's area as discussed. In various embodiments, a location directory of available wireless networks may be created. In one example, a graphical user interface allows a user to interact (e.g., via a web site) with a location database thereby allowing the user to browse a directory of available wireless networks and their respective locations. Further, the directory may indicate one or more attributes or functions of attributes. In one example, the directory identifies the expected latency of one or more wireless networks as well as the location, service offered, and whether the wireless network is intentionally shared.

Further, targeted advertising may be directed to the digital device 1002 depending on the location of the user or the user's proximity to goods and services. In various embodiments, a database of locations of wireless networks may be generated. Access to the database may then be sold to advertisers to create or direct advertisements.

FIG. 15 is another flowchart of an exemplary process for updating and storing attributes associated with wireless networks within a network database. In various embodiments, an owner of a wireless network, user of a digital device 1002, and/or administrator may log onto a web server 1018 to create, update, or access one or more network profiles. In one example, network owners registered with the web server 1018 have the ability to add information and/or attributes within a network profile regarding their own network. For example, the user may indicate that, although the network is open, it is not to be shared (e.g., storing a shared indicator that indicates that the wireless network is “not shared” within the network profile). Alternately, the user may designate their network as “shared.” Further, the user may indicate what services may be used over the network (e.g., by the performance of the network is suitable for VOIP or online conference calling but not online video conferencing). The user may also provide information regarding the location of their network device and other network devices in the area.

In another example, a user of a digital device 1002 registered with the web server 1018 may add attributes regarding wireless networks they have experience with. For example, a user of a digital device 1002 may log onto the web server 1018 to store a shared indicator that indicates a local coffee-shop network is “shared.” In some embodiments, the user of the digital device 1002 may be authorized to store an attribute to all network profiles of all coffee shops of the same chain to indicate that their networks are “shared.” In other embodiments, an administrator of the coffee-shops or an administrator of the network database may store a shared indicator indicating that all of the wireless networks offered by coffee-shops of the chain are “shared.”

In step 1502, the web server 1018 logs in a user. The user may log in or register with the web server 1018 over a network such as the Internet. In one example, the user browses to a web page to enter a username or password. In some embodiments, the connection between the user and the web server 1018 are encrypted before or after the user logs in.

In various embodiments, any user with a digital device 1002 capable of wireless access may have the option to register with the web server 1018. In some embodiments, the user is authenticated to confirm authorization. Owners of networks may have the option to change the attributes of their own network but not the attributes of any other networks. Administrators, on the other hand, may have the authorization to change attributes associated with a plurality of networks.

In step 1504, the web server 1018 receives a network device identifier and an attribute from the user or administrator. In some embodiments, the network device identifier is associated with a single wireless network. In one example, the network device identifier is a BSID identifier of a network device. In other embodiments, the network device identifier is associated with a plurality of wireless networks. For example, the network device identifier may be an SSID identifier such as “Starbucks” The SSID identifier may be shared by many network devices. In this example, every wireless network at a Starbucks coffee shop may have the same SSID identifier.

In step 1506, the web server 1018 determines if a network profile associated with the network identifier is within a network database. In some embodiments, the network database is local to the web server 1018. In other embodiments, the network database server 1012 comprises the network database. In one example, the web server 1018 provides a request for one or more network profiles that are associated with the network device identifier to the network database server 1012. In another example, the web server 1018 may query the network database directly or provide a request to the network database server 1012 to determine if the network profile exists.

If the network profile exists, then the web server 1018 or the network database server 1012 determines if the user has authorization to the changes to the network profile in step 1508. In some embodiments, the network profile comprises or is associated with security settings that indicate if the user or administrator has rights to access, view, or modify the network profile. In one example, the web server 1018 confirms the authorization of the user with the security settings. Assuming the user is authorized, the network profile is retrieved in step 1510. If the user is not authorized, the web server 1018 may provide a message indicating that the user is unauthorized to perform the requested action.

In step 1512, the web server 1018 determines if the attribute already exists in the network profile. In other words, the web server 1018 determines the type of attribute (e.g., a shared indicator, service identifier, or QUO metric) received from the user and determines if that type of attribute is already present. If the type of attribute is already present then the web server 1018 may update the attribute within the network profile in step 1514. As discussed previously, if the attribute is quantitative, the web server 1018 may average or perform a weighted algorithm on the different attributes. The result may then be stored within the network profile. In some embodiments, many attributes from the same network device indicator may be averaged or otherwise transformed by one or more algorithms and the results stored within the respective network profile.

If the attribute is not quantitative, then the existing attribute may be replaced by the new value. For example, the owner of a network may have previously indicated that the network is “shared.” The owner may log into the web server 1018, and request that the network profile for their network be updated to indicate that the network is no longer shared (e.g., replace the shared indicator indicating “shared” with a shared indicator indicating “not shared”). In another example, an administrator may be aware of a chain restaurant that offers free wireless access. The administrator may log onto the web server 1018 and request that all of the network profiles for the chain restaurant be updated to indicate that the networks are “shared.”

If the network profile does not exist in the network database, than the web server 1018 or network database server 1012 creates a new network profile in step 1516. In some embodiments, the web server 1018 checks to determine if the user is authorized to create a new network profile. The attribute associated with the network device identifier is then stored within the network profile in step 1518. Similarly, if an existing network profile retrieved did not have the same type of attribute as the one received form the user, the attribute is stored in the retrieved network profile.

It will be appreciated by those skilled in the art, that although FIG. 15 is discussed with respect to the web server 1018 and the network database server 1012, the functions described herein may be performed by any server. For example, the functions described in FIG. 15 may be performed by a single server. Alternately, different servers than those described in FIG. 15 may perform the different described functions.

In various embodiments, the web server 1018 may store personalized settings. In one example, a digital device user creates a user account on web server 1018 and stores the personalized settings. The personalized settings, as described herein, may be used by the rules server 1010 in selecting wireless networks for the user's digital device 1002. For example, when the user's digital device 1002 provides a list of available wireless networks to the rules server 1010 as well as a user identifier. The rules server 1010 may check with the web server 1018 if there are any personalized settings associated with the user identifier. If personalized settings exist, then the rules server 1010 may apply one, some, or all of the personalized settings to eliminate undesirable wireless networks and/or assist in the wireless network selection process.

FIG. 16 is a flow diagram of an exemplary process of using a network database in selecting a wireless network. By collecting the attributes into a network database from different users (as discussed in FIGS. 14 and 15), the rules server 1010 may provide accurate wireless network selections with an increased likelihood of meeting a desired level of performance.

In step 1602, the profile server may receive multiple attributes for a first wireless network from multiple users. In on example, many users access the same wireless network (e.g., a wireless network at a busy airport). Each digital device may provide attributes to a server such as the profile server 1014. The attributes may be collected over a long period or time or nearly simultaneously.

In step 1604, the server, such as the profile server 1014 averages the multiple attributes and stores the average within a network profile associated with the first wireless network. In some embodiments, the server retrieves a network profile associated with the first wireless network. The server may then perform an algorithm, including a function that averages attributes of a similar type (e.g., latency metric or bandwidth metric). The result may be stored in the network profile of the first wireless network.

In step 1606, the server receives multiple attributes for a second wireless network from multiple users. The second wireless network may be located in the same area as the first wireless network. In step 1608, the server may average the multiple attributes and store the average within a network profile associated with the second wireless network. Similar to step 1604, in some embodiments, the server retrieves a network profile associated with the second wireless network. The server may then perform an algorithm, including a function that averages attributes of a similar type and store the result in the network profile of the second wireless network.

In step 1610, the server receives a list of available wireless networks including the first and second wireless networks from a digital device 1002. In one example, the digital device 1002 scans for available wireless networks and receives network device identifiers for the first and second wireless networks. The list of available wireless networks comprising the two network device identifiers may be provided to a server such as the rules server 1010.

In step 1612, the server retrieves a network profile for the first and second wireless networks. For example, the server may retrieve the first and second network profiles based on the two network device indicators within the list of available wireless networks. The first and second network profiles comprise the results of the multiple attributes received from steps 1602 and 1604. The first and second network profiles may be retrieved from a network database comprising a plurality of network profiles.

In step 1614, the server compares the averaged attribute of the first wireless network to the average attribute of the second wireless network. In taking many attributes of a similar type from many users, the results of the averaging function or algorithm tend to be more accurate and, therefore, may be representative of an expected level of performance of the wireless networks. Similarly as the expectations of performance are more accurate, the comparison of these attributes in the aggregate may also product more accurate results.

In step 1616, the server selects an available wireless network based on the comparison. For example, by comparing the averaged attributes of the first wireless network to the average attributes of the second wireless network, the selection of wireless network with the best performance can be made with a higher confidence. As a result, as more users add more attributes to network profiles within the network database, current and increasingly accurate information may be used to help users find and utilize the high quality wireless networks. In step 1618, the server may provide the network wireless selection to the digital device.

In various embodiments, the attributes of the different wireless networks may also indicate the usage and/or quality of the wireless networks. The attributes may also indicate the services used. This information may then be analyzed and/or offered to various businesses and services. In one example, a potential business may wish to know the current usage of wireless networks in hotels, airports, and restaurants. Another business may wish to know which services are most popular in certain locations or are most popular with networks associated with a certain kind of business (e.g., convention centers). Similarly, businesses may be interested in eliminating unpopular services or wireless networks that fall below a usage threshold.
